IOMeter - Mixed Workloads with QD
In our first mixed workload, OLTP, we found the four-drive RAID 0 topping the chart at 209 IOPS. The RAID 5 and 10 arrays followed at 95 IOPS and 133 IOPS, respectively.
Moving over to file server, the RAID 5 array came in at 110 IOPS, while the RAID 10 landed at 164 IOPS. The four-drive RAID 0 peaked at 255 IOPS at QD16.
Email server had each of the RAID 0 arrays close together, from the single drive at 53 IOPS to the four-drive array at 190 IOPS. With the RAID 5 and RAID 10 arrays, we found performance at 77 IOPS and 115 IOPS, respectively.
Web server was by far the highest performing test for all the arrays. The four-drive RAID 0 was passed by our RAID 10 array by a margin of 21 IOPS.
Workstation had the RAID 0 arrays scaling quite well. The single drive setup touched 63 IOPS, while the four-drive setup reached 202 IOPS. With the RAID 5 and 10 arrays, results came in at 116 IOPS and 149 IOPS, respectively.
